Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed May 20, 1911.. Serial No. 628,539.

To all whom it may concern: a

Be it known that I, OHARLEY ELGRnnN WOOD, citizen of theUnited States,residing at McKinney, in. the=countyof Collin and State of Texas, haveinvented certain new and useful Improvements. in Razor-Strep pingDevices, ofjwhich the following. is a specification.

This invention relates to razor. stropping.

devices. a

One object istoprovide a device embodying such characteristics that therazor blade may be held upon an incline .to insurean efficientsharpening of the edge of the blade Another object resides in1theprovision of a razor sharpening device embodymg com:

paratively fewparts with the various parts constructed and arranged for.easy and quick.

cooperation and with one movable part cush ioned at each limit of itsmovement to provide for an eiiective engagement of the razor bladewitht-he strop.

With the above and other objects in view, the present invention consistsin the con: struction and arrangement of; parts herein-1 after morefully described, illustrated in the accompanying drawings 1 and;particularly pointed out in the appended claim. it being:

understood that changes may be made in the form, proportion, sizeandminor details without departing from the/spirit or sacl'i ficing any ofthe advantages of the invention. a

In the drawings :-Figure 1 is a perspec other suitable device 14 wherebythe casing.

may be secured to a book? (not shown) for operation of the device tosharpen the razor blade. The outer ends of theside pieces 1 and 2 areconnected by the pairl of rods 5 and also by the outer rods 6to preventspreading of the :outer ends of thel side pieces 1 and 2, there beingguide rollers 7 mounted on the outer rods 6 as shown.

Mounted withinthe casing for swinging movement is a frame consistingoftheends Fig. 4 is a face view. Fig. 5 is a;

8 and?) mounted on thepivot rod 1.0 which connects the side pieces 1 and2 of the casing, the end pieces 18 and 9 being connected by the rods 11and 12 on which are loosely mounted guide rollers 13 and 14 and alsoconnected by a rod 15 to which latter and adjacent the outer faces ofthe end pieces 8 and 9 are secured the legs 16 and 17 of the bladeholder 18, said legs 16 and 17 of the blade holder being mounted toswing on the rod 191which connects the side pieces 1 and :9 of thecasing substantially intermediate the ends of the latter.: By virtue ofthe particularpivotal mountings of said frame and blade holder, theswinging movement of the frame inmone direction; effects swinging:

movement of the blade holder in the opposite directionfora purposepresently explained and as Will be brought out more in detail.

hereinafter. The leg117 of the blade holder 18 is shorterthan the log 16and it will} be notedthat the difference in the length of the legsis toprovide for aninclined disposition of the blade holder 18 withinthecasing and that the blade holder instead of being dis posedstraightacross the casingis disposed upon an inclination so as toprovide for an efiicient sharpening of the blade.

Connecting the side pieces 1 and 2 of the.

oasing anddisposed upon anincline substan tially parallel with theincline of the lower edge of the blade holder 18 are inclinedlrocls.

20 and 21 onwhich are loosely mounted the ihclined guide rollers 22 and23, respectively go The blade holder 18 maybe of any, form desired, butas shown, it includes spring aws 24 and 25 and has mounted within itandsecured; in any suitable manner against the inner :face of its back aa fiat or other spring: 26 which has one end. bent to provide a 1 1shoulder 27 to limit the inward movement of. if

the razor blade 28 whichlatter is positioned in the holder through theopposite end lot the. latter and through the open1ng;29 1n the sidepiece 2 of the casin The: character 30 indicates a leather orother-strop havingits ends provided with hand or finger rings 31 and 32.Tolposition 1 the strop it maybe done in various ways,

one :way being to insert the strop between 1 the bight portion 3 and theswinging frame. 1 andlpermit the strop .tolie adj acent. opposite sidesof the casingandl onthe upper rollers a i 13 and 14 of the swingingframe. The end of. the strop having the ring 32 is then directedinwardly of the casing andunder the 1 "35 thess'trop -j Copies. bfthis patent may be obtained for inclined roller 23 and down between theroll ers 7 and the corresponding rod 5. The-other end of the strophaving the ring 31 is disa posed in like manner with respect to theopposite rod 5 and opposite rollers 22 and 7. The device is then in thecondition illustrated in the drawings andbyengaging the attaching means4 to a hook (not shown); and pulling von opposite rings 31 and 32alternately the 10 strop is worked back and forth. In workingthestropzback and forth and the strop being.

mounted on the swinging frame the latter caused to swing in oppositedirections on its pivot 10 according to the pull onopposite ends offthestrop. This swinging movement of said'frame causes swinging movement ofthe inclined razor blade holder 18 in a di-' ;;;rection oppositetotheswinging movement of ,the frame. For instance by pulling ,O'utr' 20wardlyv. on the ring, 32 the "frame will be caused to swing :to the leftwhichwill result the blade holder being swung to :the right, gasvvill beseenin Fig. 15 and causing; the i b1ade 28 to be thrownagainst theinnerface of the strop; By thennpulling'on the ringi.

' '31 Ithe frame will swing in the opposite di: rection ;;and cause anopposite swinging movement of the razor holder to dispose the s blade 28against the inner face of the oppo- 30 1 site side of the strop.- Inthis way, the blade- I ,m'ay ibeieffectively sharpened to give it aproper shearingedge rather than a straight 7311p and down edge aswhe'nzthe holderis'disposed to present. :the blade straight across Theswinging movement of the 'frame is cushioned by means of the lugs 33 and3t '1 -f11whichiproject through the openings 35 and 136 of theend piece2 and which are formed.

4Oby bending; the extremities ofthe spring: rmemberi '35 secured bysoldering; orrin' any;

i suitable manner to the outer face 'of' the'end lof'the'casing, thelower reduced'part' d; piece 9 of the swinging frame be- T ing sodisposed as to engage said lugs 33 i I and 34 alternately according tothe swinging a movement of the frame and the openings 7 through.xWh-lGll said lugs project being (of such size as to permit movement ofthe lugs, L

in the openingsyand effect an efiicient cush ioning action against theswinging frame.

This cushioning "actionipermits the blade to be pulled in proper tightengagement with the strop without danger of breakingany; part ofthedevice. What is claimed is':-
